Abstract

Alzheimer's disease (AD) is a major public health problem with substantial economic and social impacts around the world. The hallmarks of AD pathogenesis include deposition of amyloid β (Aβ), neurofibrillary tangles, and neuroinflammation. For many years, research has been focused on Aβ accumulation in senile plaques, as these aggregations were perceived as the main cause of the neurodegeneration found in AD. However, increasing evidence suggests that inflammation also plays a critical role in the pathogenesis of AD. Microglia cells are the resident macrophages of the brain and act as the first line of defense in the central nervous system. In AD, microglia play a dual role in disease progression, being essential for clearing Aβ deposits and releasing cytotoxic mediators. Aβ activates microglia through a variety of innate immune receptors expressed on these cells. The mechanisms through which amyloid deposits provoke an inflammatory response are not fully understood, but it is believed that these receptors cooperate in the recognition, internalization, and clearance of Aβ and in cell activation. In this review, we discuss the role of several receptors expressed on microglia in Aβ recognition, uptake, and signaling, and their implications for AD pathogenesis.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • FCγR activation promotes Aβ clearance via phagocytosis.

    “FCγR activation also promotes Aβ clearance via phagocytosis [139, 140].”

    From Microglial function, INPP5D/SHIP1 signaling, and NLRP3 inflammasome activation: implications for Alzheimer’s disease (2023) · cites this paper as [140]

    The Fc receptors section says microglial FcRs mediate Aβ phagocytosis in the presence of antibodies, supporting the proposed clearance pathway. The citing sentence omits that condition; the same section also notes that some antibody-associated Aβ clearance is not FcR-dependent. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Aβ fibrils increase inflammation.

    “Aβ fibrils also increase inflammation148 (Fig. 5, purple), which may unanchor residual PDE4A125, and further disinhibit stress signaling pathways.”
  • In mouse macrophages and COS cells, SHIP1 activates the ITIM of the inhibitory receptor FCγRIIβ, which inhibits the activating receptor FCγRIIA to block FCγRIIA-mediated phagocytosis.

    “In mouse macrophages and COS cells, SHIP1 was shown to activate the ITIM of the inhibitory receptor FCγRIIβ, which inhibits the activating receptor FCγRIIA to block FCγRIIA-mediated phagocytosis (Fig. 3C).”

    From Microglial function, INPP5D/SHIP1 signaling, and NLRP3 inflammasome activation: implications for Alzheimer’s disease (2023) · cites this paper as [140]

    The Fc receptors section (page unavailable) says Fc receptor engagement can activate phagocytosis, but it does not address the claimed inhibitory mechanism. Searches for SHIP1, ITIM, FcγRIIβ, FcγRIIA, and COS cells found no passage describing that mechanism in our copy. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • SHIP1 directly inhibits FCγRIIA by binding to its ITAM, which prevents activation of PI3K.

    “SHIP1 also was shown to directly inhibit FCγRIIA by binding to its ITAM (Fig. 3C), which prevents the activation of PI3K [134, 137–140].”

    From Microglial function, INPP5D/SHIP1 signaling, and NLRP3 inflammasome activation: implications for Alzheimer’s disease (2023) · cites this paper as [140]

    The Fc receptors section discusses FcγR signaling in microglia, and the References section lists a study of PI-3 K in that context. Our copy does not address SHIP1 binding the FcγRIIA ITAM or preventing PI3K activation; searches for SHIP1, ITAM, and FcγRIIA found no passage establishing that mechanism. (LLM, conf=0.72)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
